I knew the location from last season, but I hadn't remembered the pavilion/overhang, and not the fact that there was writing on it. My bad. I'll go check out the season 2 threads to see what I can find....

Hmm... I assumed BRB meant Miles' boat house which is clearly just down the street....?

The Barracks is in the middle of the island, yet the sub seemed to be close to it. Also there is a boat house where Miles is being kept.If it isn't near Pala ferry, where is it? Is there a huge river/lake close to the Barracks that connects to the ocean?

I assume that the boat house and the sub dock are both on the same inlet area. The one we saw when Juliet arrived. We did not get a full 360 view of the area. This does appear to be a small hike from the houses from the view at the start of season 3. Plus we know Alex had to show Locke how to get there. So it must be a hike.The Pala Dock must be somewhere else since Sayid, Sun etc walked home from it. THis is not fact, just my logic.
